GuiM-eration has for its objeetgtn furnish asn-improved apparatus, dui-ohio and simple in construction, for aepaxting the girain'fron: the' straw :is they come from the threshing machine. And it consists inthe combinn'tion of the alottednnrl-perforated :stationaryv eepnrgxtonbonrds, and the toothed beater-bare with each other, with the cranlr-nhafts,'and with the rnmeof the machine, when the enirl boards and beaters are constructed-and operated substantially as hereinni'ter.more` fnlljY described. s

A is the frame'er Vexigent' the ninehiney long tho-bottom of .vhich the grain posses to the cleaning-mili. B are two c'xankrheereifotrmg'in Uear'mgn m-tllcnrlesfomid'a*ohemchine, and 'which are plece'd'the one in the forward and the other in thc back port of said machine. To thecnds of the shaft B, projecting through one of the' sides, as a?, Aare attached drive-wheels, C, which are connected to 'each other` hy the pitman D, so. that the seid wheels nml cronica muy revolve together. E are the beeters or bars which ore 'attached tothe crankahafts B, or to a mme, F, attached to said-shafts. The dmgsvings represent the bcc-ters E as being attached to a frame,'F, but we prefer to connect-them directly to the crank-shaft, ne being more simple in eonstrnctionland 'eqnally,eective. From the upper eide of the beaters `E project teeth, e', which take hold of the straw and carry it forward with the forward. mo'vemento the said beaters E. G are the scparotor-hoords, whichnre'secnred to the frame A of the machine in auch a.' position -thot the beaters E may risethrongh and alittle above'the said 'boards in their upward and' forward movement. The sepamtor-boards G should he from four to six inche wide,

and should be placed at n distance apart equal to the Athickness of the beetern'E, so that the slid beaters may niovo freely between the seid boards, ne'shown in iig. 2. The boards G are perforated with one or Amore rows of holes, one side oi said `holen being bcv clled o', to allow the grain Vmore emily to nd its way into'end through them, as shown in tige. -Il, 2, und 3.' When operated, the beaters E rise through .the'slots between the boards G,

striking the strow e smart blow on its umleisidc, jarring ont.' the grain, and carrying the spaid etrawforwsrd the length of o stroke. The stronthen lies nt-st until the bentersagain rise end operate upon Vit. f'l'he groin, when separated from the strekt', posses down Athrough tlieopenings 4in: the boards Gto the bottom a of the machine, along which it pensee to the cleaning-mill, The machine ie 'driven by'the sc me power that drives the threshing machine end 'dashing-mill, in connection with which it is-usei, and should be set with its open end towards the cleoning-nxill, ond at auch an inclination that the groin moy pees freely along its bottom, a, tothe said mill.

We claim as nemend deirentoeenurejby Lettere Patent-'f- The separator-bosrda'; perforated with holes, one eide ci' each hole being bevelled o', es herein described, the reciprocotingbeatersEotcclecl to the frame F upon the crankshaft B, eo that at eaelrrovolntion of the .said crank-shaft B, il the beaters moy pass nt theV same time through the separator-hoorde, when all are com strncted and arranged en herein niet forth.
